Cerritos Magnetic Lock Installation Built Around a Safe Exit

Short answer: A maglock has no latch, so exit rules drive the design. For people to leave without special knowledge, an exit-side motion sensor, a push button and a fire alarm release normally cut power to the lock, and a power failure frees the door. Your fire marshal or building department has the final say, and we design around it.

Magnetic Lock Installation in Cerritos, CA — Installing an electric strike for access control

A maglock is installed from the header down, and most of the work happens above your head: drilling the frame, setting brackets, pulling low-voltage cable through the ceiling and landing wires at a power supply. We schedule magnetic lock installation in Cerritos around your hours, starting as early as 6:30 a.m. every day, so a shop can be secure before it opens. We work until 11:30 p.m., weekends included. Tell us the door type, how it swings and who needs to get in. A few photos of the header and door edge help us arrive with the right bracket kit.

Magnetic Lock Installation in Cerritos: what to expect

Doors dictate the hardware. An outswing steel door with a solid header takes a standard header-mount lock easily. An inswing door usually needs a bracket kit so the magnet and plate meet squarely. Aluminum storefronts have narrow headers and thin extrusions, so the magnet may need a through-bolted backing plate or may be better as a concealed shear lock. Tempered glass can't be drilled once it has been made, so glass doors use clamp-style brackets that grip the glass without any holes. Double doors need either two magnets or a combined unit, plus a plan for the inactive leaf. Wood doors need through-bolts long enough to resist pulling out. We look at the door, the header and the swing during the survey and choose the mounting kit before you see a price, because it is often the largest piece of magnetic lock installation. If the header cannot carry a magnet, we say so and suggest another route.

Work included on a typical visit

  • Inswing doors, brackets and offset mounts. When a door swings into the secured space, the magnet and plate can't meet face-to-face without help. Bracket kits offset one or both parts so they close squarely. We pick the kit based on door thickness, header depth and swing, then test with the door fully open, closed and under pressure.
  • Aluminum storefront doors and shear locks. A storefront in the shopping centers around Cerritos usually belongs to the landlord, so we plan the mounting around what is allowed. We measure the header, look at glass stops and hardware, and recommend surface or shear mounting based on depth, appearance and budget.
  • Double doors and paired magnets. Double doors need two locks or a combined unit, one per leaf, plus a plan for the inactive leaf. We align both plates and magnets so each pulls evenly, then check that the meeting edge keeps the leaves from flexing apart. Both leaves release together when power is cut.
  • Fire alarm release and code review. A fire alarm release uses a relay from the panel to cut lock power when the alarm activates. We install the relay on the lock's power line and test it with your fire alarm contractor, who has to trigger the panel. When building rules require sprinkler release too, we plan for that.
  • Readers, keypads and controllers. A maglock pairs well with almost any credential: cards, fobs, PIN codes, mobile credentials. What matters is that the controller's relay is rated for the lock and that the exit path never depends on that relay. We match the pieces, then test each credential type.

How Cerritos shapes the job

Dealerships use maglocks on key rooms, parts cages and glass doors between showroom and service areas. A key room is the most sensitive, since it holds every key on the lot. We pair the lock with logging, door-position monitoring and a clear exit, and tie it into your key-control routine so a door left ajar draws attention before it becomes a problem.

Shopping-center tenants use maglocks mostly on stockroom, back-of-house and office doors, and sometimes on glass entry doors after hours. The storefront frame belongs to the landlord, and exit rules apply to the rear corridor too. In Cerritos centers we check delivery routes, fire alarm tie-ins and the way back doors are really used, because a maglock that traps an employee carrying inventory is a problem waiting to happen.

Condo lobbies often have glass doors, an elevator lobby and a garage pedestrian entry, all managed by volunteers on an HOA board. Magnetic lock installation here needs documentation: model, holding force, wiring diagram, battery dates and who tests the fire alarm release. We leave a clear record so the next board can service the system without starting from scratch, and the board knows what to ask for at budget time.

Situations this covers

  • Consider an office whose doors fell open during a blackout. The cause was a small plug-in adapter with no backup feeding two maglocks. We'd replace it with a fused, regulated supply, add battery backup so the doors hold through short outages, and recommend a mechanical keyed lock for off-hours security, so protection no longer hangs on one adapter.
  • Imagine an aluminum storefront in a strip center with a header only a few inches deep. The tenant likes the look of a concealed lock. We'd compare a surface magnet with a backing plate against a shear lock, explain the cost difference and the header depth required, and get the landlord's approval before drilling a frame they own.
  • Suppose a heavy glass door slowly sags on its pivots, so the plate no longer meets the magnet squarely and the door pulls open with a firm tug. The lock isn't weak; the door has moved. We'd adjust or replace the hardware that holds the door, realign the plate, and confirm full contact before blaming the magnet.
  • A common puzzle: the door releases, yet it feels stuck for a second. That is residual magnetism, often from a worn armature plate, rust, or a plate tightened too hard. We'd inspect and clean the faces, check alignment, replace the plate or fit a spacer if needed, and verify the door falls free the instant power is cut.

From your call to the finished job

  1. Survey the door, header and exit path. We look at the door type, how it swings, the header and frame, the glass, the closer and the hinges. Then we trace how a person leaves: where they stand, what they reach for and what could stop them. The exit comes first because everything else depends on it.
  2. Design the release path and quote. We also confirm authority to modify the door. We need ID and proof that you own or manage the property, and tenants should have their landlord's permission, since mounting a magnet means drilling the frame.
  3. Mount the magnet and armature plate. Mounting is about alignment and solid anchorage. We check that the plate meets the magnet fully with the door closed and under slight pressure, that fasteners are tight and that nothing rattles loose. Glass doors use clamps; metal and wood doors use through-bolts.
  4. Run the power, sensors and fire alarm release. Low-voltage cable runs from the lock to the power supply, sensors, button and controller. We route it through the ceiling or a raceway, keep power and signal wires neatly separated, and label both ends. Fire alarm relays go in the lock's power line and are tested with the alarm contractor.
  5. Program credentials and set the timers. Programming depends on the controller. A standalone keypad takes a few settings; a networked system takes a user list and schedules. We create the first credentials with you, show you how to add and delete them, and leave the settings recorded.
  6. Test every release and hand over. We walk through the door as a stranger would, looking for anything confusing. Then we show your staff the button and the sensor, give you the wiring record and tell you who to call about the alarm panel.

Pricing factors

  • Door type and mounting hardware. A steel outswing door with a solid header is the simplest mounting. Glass doors need clamp brackets, inswing doors need offset kits, and aluminum storefronts may need backing plates or a concealed shear lock. Mounting hardware is often the biggest single part of the price, so we choose it first.
  • Exit devices and fire alarm interface. The exit devices are not optional extras. A sensor, a push button and a fire alarm relay come with almost every maglock on an exit door. They add parts and labor, but they keep the door safe and inspectable. If a fire alarm contractor must make the panel connection, that is a separate cost.
  • Power supply, backup and controller. Backup power is the most common optional upgrade. It keeps doors secure through short outages, but the batteries need replacing and the door still releases when they run out. We explain the tradeoff and price it separately. Decide what you are protecting, and for how long, before choosing battery size.

Practical tips before you call

  • Walk the door as it stands. Does it close fully by itself? Does it sag? Does the closer slam it? A maglock can't fix a door that doesn't meet the frame. Adjust the hinges and closer first, because the plate and magnet need to meet flat every time.
  • Review who holds access a few times a year. Cards and codes pile up as staff, vendors and contractors come and go, and every extra credential is a door that opens for someone. Remove what you no longer need and keep a short list of current holders.
  • Tell your alarm company before we test the fire alarm release. Tripping the panel can notify the monitoring station and even the fire department, so the alarm contractor needs to schedule it or put the system on test. That is why this part of the job is arranged ahead of time.
  • If you rent, ask the landlord in writing before anyone drills the frame. A maglock may need removal when you leave, so keep a copy of the wiring diagram, the model information and any hardware that was taken out. The next tenant, and your landlord, will thank you.

Mistakes to avoid

  • Drilling tempered glass. Once glass is tempered it can't be drilled or cut, and any attempt can shatter the panel. Use glass-door clamps that grip the edge. If a door was drilled previously, we can judge whether existing holes can be used safely.
  • Using a maglock where the door must stay latched. Fire-rated doors, some stairwells and other openings need hardware that latches positively, which a maglock does not do. Ask your building department before you specify one. If you are not sure how your door is classified, look for a label on the edge of the door or frame.
  • Installing the lock without an exit plan. A maglock with a card reader and nothing else can trap people if the controller fails while the lock stays energized. A sensor, push button and fire alarm release aren't optional on exit doors, and an inspector will look for them.

Frequently asked questions

Can a maglock be used outdoors?

Only models rated for outdoor exposure. Rain, dust, salt air and sun wear out standard indoor magnets. Outdoor-rated units, sealed wire entries and drip protection help, and corrosion-resistant plates matter near the coast. Exterior doors also see more wind and slamming, so the mounting has to be rigid, with the wire entry sealed against water.

How long does magnetic lock installation take?

A single door with easy cable access is often a same-visit job. Glass doors, double doors, long cable runs, fire alarm coordination and inspections take longer. We give you a realistic schedule with the quote and plan around your hours so the door isn't left unsecured. Our day starts at 6:30 a.m. every day.

Can a magnetic lock work on double doors?

Yes. Double doors use either two magnets, one on each leaf, or a combined unit for pairs, with a plan for the inactive leaf. Both locks release together on one circuit, and the exit sensor and button must cover whichever leaf people will use to leave. We map that out during the survey.

What happens to a maglock when the power goes out?

It lets go. A magnetic lock holds only while powered, so a blackout, tripped breaker or failed supply releases the door unless battery backup keeps it energized. That is good for exit safety and a risk for security. We discuss backup batteries, a mechanical key lock for off-hours and, if the door must stay locked, a strike or electrified lockset instead.

Do I need both a motion sensor and a push button?

On most exit doors, yes. The sensor releases the lock when someone approaches; the push button is a second, independent route that interrupts power directly. Some jurisdictions require both, and a single device is a single point of failure. Your fire marshal or building department has the last word, and we build to what they expect.

Do magnetic locks use a lot of electricity?

A single lock draws only a few watts, but it draws continuously while the door is locked, unlike a strike. Several doors on one supply add up, which is why we size the supply and any battery backup for the total load. A properly sized supply also keeps voltage steady at the magnet, protecting holding force.

How far is Cerritos from your base?

Cerritos is about 65 miles from our San Bernardino base, roughly 66 minutes in light traffic. Arrival time depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
